CVE-2024-49829 is a medium-severity buffer overflow vulnerability classified under CWE-120, affecting multiple Qualcomm Snapdragon platforms and related wireless connectivity modules. The vulnerability arises from inadequate validation of buffer lengths during context user dumps, leading to potential memory corruption. Specifically, the flaw occurs when the system copies data into a buffer without properly checking the size of the input, which can cause an overflow of the buffer's allocated memory space. This can result in overwriting adjacent memory, potentially allowing an attacker to execute arbitrary code, escalate privileges, or cause denial of service by crashing the affected component. The affected products include a range of Snapdragon mobile platforms such as Snapdragon 8 Gen 1, Snapdragon 429 Mobile Platform, FastConnect 6900 and 7800, and wireless connectivity chips like WCD9380 and WCN3620. The CVSS v3.1 score is 6.7, indicating a medium severity level, with the vector string AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. This means the attack requires local access with low attack complexity but high privileges, no user interaction, and impacts confidentiality, integrity, and availability significantly. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's exploitation requires an attacker to have high privileges on the device, limiting remote exploitation but posing a risk if local privilege escalation is achieved. The flaw could be leveraged in chained attacks or by malicious insiders or compromised applications with elevated rights to further compromise device security or stability.

For European organizations, the impact of CVE-2024-49829 is significant primarily in environments where Qualcomm Snapdragon-based devices are used extensively, such as mobile workforce devices, IoT deployments, and embedded systems relying on these chipsets. The vulnerability could lead to unauthorized access to sensitive data, disruption of critical mobile communications, or device instability. Given the high confidentiality, integrity, and availability impact, organizations handling sensitive personal data (e.g., GDPR-regulated data), critical infrastructure, or secure communications could face data breaches or operational disruptions. The requirement for local high privileges reduces the risk of widespread remote exploitation but does not eliminate insider threats or risks from malware that can escalate privileges. In sectors like telecommunications, manufacturing, and public services where Snapdragon-powered devices are common, exploitation could undermine operational security and trust. Additionally, the lack of available patches increases the window of exposure, necessitating proactive risk management.

To mitigate CVE-2024-49829, European organizations should implement a multi-layered approach: 1) Inventory and identify all devices using affected Qualcomm Snapdragon platforms and wireless modules. 2) Restrict local administrative access to trusted personnel only and enforce strict privilege management to prevent unauthorized elevation. 3) Monitor for unusual local activity that could indicate exploitation attempts, including anomalous memory usage or crashes related to context dumps. 4) Apply any forthcoming vendor patches or firmware updates promptly once released by Qualcomm or device manufacturers. 5) Employ endpoint detection and response (EDR) tools capable of detecting exploitation behaviors associated with buffer overflows. 6) For mobile devices, enforce mobile device management (MDM) policies that limit installation of untrusted applications and enforce security baselines. 7) Conduct regular security awareness training emphasizing the risks of privilege escalation and insider threats. 8) Collaborate with vendors and suppliers to track patch availability and coordinate timely updates. These steps go beyond generic advice by focusing on privilege restriction, monitoring, and proactive device management tailored to the affected platforms.
